Patented Apr. 23, 1940 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to a fiddle bow and one of the objects is to utilize a single length of thread in the formation of the bow string, simple and efficient means being provided whereby the thread is connected to the bow and additional means of new and novel construction being utilized for placing the string under tension.

With the foregoing and other objects in view, which will appear as the description proceeds,

the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein described,

16 may be made within the scope of what is claimed,

without departing from the spirit of the invention.

In the accompanying drawing the preferred form of the invention has been shown.

20 In said drawing:

Figure 1 is a side elevation of a fiddle bow constructed in accordance with the present invention.

Figure 2 is a bottom plan view of the struc- 25 ture shown in Figure 1.

Figure 3 is an enlarged view partly in elevation and partly in longitudinal section, portions being broken away.

Figure 4 is an end elevation.

80 Figure 5 is a section on line 5-5 of, Figure 3.

Figure 6 is a detailed view of one of the tension devices.

Referring to the figures by characters of reference I designates the main bow member provided at its ends with integral heads 2 extended toward each other to provide flat surfaces 3 on which are mounted tension plates 4 each having side flanges 5. Each plate has a bearing rib 6 extending transversely of one end, this rib being seated in a groove I in the head. Those ends of the plates 4 nearest the free ends of the heads 2 extend across feed nuts 8 which are seated in the heads and each feed nut is engaged by an adjusting screw 9 the head II] of which is exposed between head 2 and body I of the bow.

Extending outwardly from. each end of the body portion of the bow is a knob II made integral with the bow and constituting a means for 6 anchoring the bow string I2. This how string is formed of a single length of thread of any desired size, the thread being wrapped about the end knobs I i and stretched back and forth along and between the tension plates 4 until the band 0 made up of the width of thread is brought to the desired transverse proportions. Following the wrapping of the thread longitudinally of the bow in this manner the plates 4 are adjusted outwardly by means of the screws 9 and during this adjustment they will swing about the ribs 6 as fulcrums. Thus the lengths of thread between the plates will be placed under desired tension.

As shown in the drawing the bow can be suitably ornamented with brilliants I3 and small flags I4, the pins I5 carrying the flags being seated in recesses I 6 formed in the end portions of the bow.

What is claimed is:

A fiddle bow comprising an elongated body member having a head at each end, knobs extending in opposite directions from the respective heads, said heads being extended toward each other and having portions overlying and spaced from portions of the body member, tension plates mounted on those portions of the heads extended toward each other, said plates having exposed longitudinal channels, adjusting screws extending through said portions of the heads and exposed between the heads and the body member, said screws being positioned to thrust against and tilt'the plate, and a single length of thread mounted on the knobs and having closely lying parallel portions seated in the channels of the plates and extending between the heads, said 40 portions comprising a band, said plates being positioned to adjust the tension of the band when the plates are tilted.
